Will,
No that is not the right PMU module. Family 6, model 14 is an
Intel Core Duo/Solo. This processor is not based on the Intel Core
micro-architecture but on Yonah. It implements the architectural
perfmon v1. Perfmon2 can automtically detect it and use the
perfmon_intel_arch module.
oh, so the check should be in the pfm_p6_probe_pmu()? Like the attached patch?

Hi,
We installed a perfmon2 enabled kernel on a Intel Core machine laptop. Note
this is not a Core 2 machine. permfon2 did not identify the processor as a
Core processor. Looking through the code it appears that the family 6 model
14 processors are not identified or supported. The attached patch should
enable proper identification of the processor.
